Read “Link the Ideas” on page 63 of the textbook for a description of radical functions.

In Try This 2 you will see how radical functions can be represented using tables of values and graphs.

Try This 2

Graph

1. What restrictions are on x in the function
2. Make a table of values. Are some values of x easier to use than others? Carefully choose the values of x and record these values in a table like the following. Calculate the y-values and record them.

    

   x	y
   0	0

3. Use Grid Paper Template, which is also available in the Toolkit. Sketch the graph.
4. State the domain and range of the graph. Why do you think the domain is restricted?
